Abstract
An organic light emitting diode (OLED) device. The OLED device comprises a transparent substrate, a plurality of anodes, an organic functional layer, a black layer and a plurality of cathodes. The anodes are positioned over a transparent substrate. The organic function layer is positioned over the transparent substrate covering the anodes. The black layer is positioned over the organic functional layer and the cathodes are positioned over the black layer. Through the black layer, the amount of back reflection of external light is reduced and the contrast of the display device is increased.
